Which of the following describes the entropy change of a gas reaction? O A. If there is an increase in the number of gas molecules, then AS< 0. OB. If there is an increase in the number of gas molecules, then AS = 0. O C. If there is an increase in the number of gas molecules, then AS> 0. O D. The change in entropy cannot be predicted in a gas reaction.​

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
